I like the theme of space in this poem because it sounded initially like it would be talking about restrictions, but you really turned that around in a sort of unexpected way, speading ideas out and showing how there's no limit to this world and we're just getting smaller and smaller...

I don't like the length of this poem because it drags a little, losing ideas and essence. After awhile, I start wondering where the end is. Perhaps stanzas would help, but I feel somehow they won't. You do start getting a little cyclic.
